The streetsign is an iconic weapon in the Madness Combat series. It is shaped like a stop sign, but with an exclamation mark. Originally just an odd streetsign, it later becomes something of Tricky's signature weapon.

The streetsign made its first appearance in Madness Avenger on the twisted streets of Nevada after the Sheriff activated the Improbability Drive. Hank pulled it out of the ground and used it to beat to death a group of grunts and the Sun. Hank finally impaled Tricky through the chest with the sign. After his resurrection, Tricky later tried to attack Hank with the sign but failed to land a blow and was promptly killed.

The streetsign made its next appearance in Madness Depredation. While Hank and the 1337 crew were in a heated battle at the bottom of a canyon, the streetsign shot out of the ground, then raced off-screen, creating a large crack in the ground. From this crevice emerge a few 1337 agents and, ultimately, Tricky. Tricky used the streetsign to battle Hank, armed with a dragon sword. Tricky successfully managed to impale Hank with the sign before dropping it when part of his skull was hacked off.

The streetsign, covered in blood, was still being wielded by Tricky in Madness Antipathy, who was conducting a train. When Hank jumped from the front passenger car to the locomotive, he grabbed onto the sign. While Tricky was trying to shake Hank off, the locomotive was running off a cliff. After the train crash-landed on the other side of the gorge, Hank and Tricky dueled, with Tricky using the streetsign more offensively than before. He even managed to stab Hank through the neck with it, killing him instantly before resurrecting him again. The sign was last seen on the ground near the hot dog vendor's stand.

The streetsign reappeared in Incident: 1000A, wielded by Tricky to distract Hank and bludgeon Sanford to death.
